So some things require JavaScript. That's okay. Basic navigation in our default skin should, however, not be one of those things. Not only is the wiki network menu (#site-info) and the wiki-specific content navigation unusable, but more importantly, the login/sign up links are not easily accessible. Obviously we can't dump everything into MediaWiki:Sidebar either.
@Isarra Do you have some good ideas on how to implement this? GreyStuff and Timeless both seem to work just fine without JS, as they should.
